Abstract (en)

[origin: US5021473A] Process for enhancing the electrostatic chargeability of powder coatings or powders, and the use thereof for surface coating solid objects. Process for enhancing the electrostatic chargeability of powder coatings or powders intended for the surface-coating of solid objects, by homogeneously incorporating at least one salt-like, cationic compound of the formula (1) <IMAGE> (1) in which R1, R2, R3 and R4, independently of one another, denote hydrogen atoms, straight-chain or branched alkyl groups having 1 to 30 carbon atoms, mononuclear or polynuclear cycloaliphatic radicals having 5 to 12 carbon atoms, oxethyl groups of the general formula -(CH2-CH2-O)n-R in which n denotes a number from 1 to 10 and R denotes a hydrogen atom, a (C1-C4)alkyl or acyl group, furthermore denote mononuclear or polynuclear aromatic radicals or araliphatic radicals, where the aliphatic, aromatic and araliphatic radicals may be substituted, and where the alkyl, cycloalkyl, aralkyl and aryl radicals for R1 to R4 may be substituted by halogen atoms, X denotes a phosphorus, arsenic or antimony atom, where, in the case where X denotes an arsenic or antimony atom, at least one of the radicals R1-R4 is not a hydrogen atom, and A(-) denotes the equivalent of an inorganic or organic anion, in an amount from about 0.01 to about 10 percent by weight into powder coatings or powders, the salt-like, cationic compounds of the formula (1) being dissolved or dispersed in the powder of coating system.
